Tests of the consistency between binary gas adsorption isotherms and. binary chromatographic retention volumes

The amounts of two gases simultaneously adsorbed on a solid can be measured directly or may be inferred from chromatographic retention times. Adsorpti on isotherms obtained by the two methods should agree within experimental e rror. It is desirable to have a quantitative test of the degree of agreemen t between experimental results made by both methods. We establish here a ne w adsorption function and relationship that should exist between the measur ed retention times and static data if both methods and the experimental res ults are in perfect agreement. This function gives a test of consistency be tween static data and retention times that has advantages over alternative methods.
